Problems with mock rawhide builds

I'm seeing the following error in my x86_64 rawhide mock builds in root.log: DEBUG util.py:250: /usr/bin/python: relocation error: /lib64/libnsl.so.1: symbol __libc_clntudp_bufcreate, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference If I wipe out the mock cache it will work. Any ideas? Anyone else seeing this? mock host is running CentOS 5, also seen with F-8. mock 0.9.7-1.el5.
